[RE-wrenches] EG4 battery OK with Magnum electronics?

[Mick Abraham]

Hi, Mechanix~ A longtime client has a Magnasine 4024 inverter/charger,
PT-100 charge controller, BMK battery monitoring kit & the ARC Advanced
Remote with 4.0 firmware.
He'd like to upgrade from L-16 floodies to five of the EG4 LL24V 200 AH
batteries in a cabinet.

I've reviewed the EG4 info for care & feeding, alongside various menus in
the Advanced Remote manual, and it looks like the Magnum setting ranges are
compatible. Before shipping out the money,
I'd like to know any feedback from the Wrenches about how things are
working when these product families are combined.

At times I've noticed strange behavior with the Magnasine inverters during
charge cycles. As I recall, the units jump from Bulk to Float soon after
generator driven charging gets under way. For clients with old or
compromised lead acid floodies, I've occasionally set Float and Bulk to the
same target voltage. These are off grid setups where the generator noise
keeps the client aware that charge is underway. Most of these clients don't
have the generator automated, which is also true for my 2025 EG4 customer.

I won't try that "Float @ Bulk voltage" trick with lithium, of course. Any
& all war stories would be welcomed. As always, "The Wrench List is the
Bomb!"
